MJ Logs has been gathering well logs all over North America since 1971. We have assembled one of the industry’s most complete, highest quality, depth registered well log libraries available with 7 million logs. This tremendous collection covers 27 States and Canada. Areas are constantly updated with new releases, keeping the library current and up to date.
